ds1820的源码驱动-The source driver ds1820

首先再次声明我是菜鸟，我写出来的目的是给没有接触过lcd的朋友看得，我本人水平有限，错误在所难免，欢迎指出。-First of all, once again declare that I am a rookie, I write is designed to not come into contact with lcd friends to see, I am limited, error is inevitable, welcome to point out.

430用IO口模拟SPI读写的驱动程序。包括SPI的字节读写，区块数据的读写等功能-430 IO I used to read and write the simulation SPI driver. SPI including the byte read and write, read and write data blocks, such as functional

在Keil环境下，用1302实现的时钟，用6位数码管显示时间,显示格式00:00:-In the Keil environment, to achieve by 1302 the clock, with six digital display time, display format 00:00:00

基于pic系列单片机的，R61505U的lcd驱动芯片代码。-Pic microcontroller-based series, R61505U the lcd driver chip code.

本例中含有电路图及程序，单片机的仿真也含其中，很有用哦-In this case contains circuitry and procedures, including single-chip microcomputer in which the simulation is also useful Oh! !
